Bug: Travel Distance keeps increasing after accumulation stop

Hi,

There seems to be a bug in the update of the totaltraveldist when Task Executers stop on an AGV network due to accumulation.

In the attached demo model, we ensured that TaskExecuter10 is placed on the network backwards and in front of the other two TEs. Since it is travelling more slowly, it is causing the two TEs behind it to stop and start. Every time they stop the totaltraveldist is reduced, but when they restart it is not increased by the same amount.

By the time the task executers reach the sink, TE10 shows the correct distance of approx. 40 meters, but the statistic for the others is at > 300 meters.

This issue is present in all versions from at least 19.0 through 20.0.2.

Software Version:

FlexSim 20.0.2

This sounds like a bug to me. I'll put it on the dev list.

Same problem, versión 20.0.

After a loop, TaskExecuter1 gives the correct Total Travel Distance, but the second (which is faster due Empty - Loaded behavior) gives a totally wrong number.

Hi @Jordan Johnson, I just checked my original demo model in 20.0.7. Is it correct that this bug is still on the dev list? :-)

Hi @jordan.johnson, I just ran the model again in 20.2.1 and it seems to work now, but I cannot find it in the release notes... can you confirm that this issue was fixed and in which version? Thanks!
